Is this a bug? login.keychain.bak shouldn't have been detected as Tripcode DES.

Which Operating System are you using? You might be able to use
pre-compiled JtR versions depending on your OS.
For cracking OS X Keychains (which you seem to be doing) you need
jumbo version of john. You can get it from
https://github.com/magnumripper/magnum-jumbo. After doing "git clone",
build john, run keychain2john program on login.keychain.bak file and
then run john on the output of keychain2john.
Another option is to obtain OS X hashes (using lion2john.pl program,
included with john-jumbo) and crack those to figure out the login
password. This option will be way faster than trying to crack the
Keychain.
(Compile keychain2john using command "gcc keychain2john.c")

First run keychain2john on your keychain file and then run john on the
output of keychain2john.
